To all whom t may concern.'

Be it known that I, JACOB I-I. HUMBURG, a citizen of the United States,residing at Mount Angel, in the county of Marion, State of Gregon, haveinvented a new and useful manufactured for a small cost and sold at areasonable profit.

A further object of the invention is to provide an improved hingeconsisting of a pair of hingedly united Ushaped links, one connectedhingedly or pivotally to the door, and the other pivotally connected tomembers of the jamb of the door, whereby, when the door is closed andthe U-shaped links disposed so that the pivotal connection of one of thelinks of the jamb protrudes between and outwardly beyond a plane fromthe pivotal connection between the links and the pivotal connection ofone link to the door, whereby the door is held in place.

A further object of the invention is the provision of an improved latchfor the other side of the door.

In practical fields, the details of construction may necessitatealterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a view in elevation of a portion of a silo,showing the improved hinge and latch applied to the door of the silo.

Fig. 2 is a sectional view on line 2-2 of Fig. 1.

Fig. 3l is a similar view showing the latch released and the hingedconnections partially moved in full lines and completely moved in dottedlines, showing the door swung on the inside of the silo.

Referring more especially to the drawings, 1 designates the portion of awall of a silo, which is provided with a door opening 2, and secured tothe outer face of the wall and adjacent to and overlying the marginaledge of the opening to form the jamb shoulder 8, are the vertical andtransverse cleats 4 and 5. Engaging the door opening and the shoulder 8thereof is a door 6, and secured to the -outer face of the door by thebolts 7 are the vertical cleats 8 and 9, which are reinforced by thetransverse rods 10. Shanks 11 of the eyes 12 extend through the cleat 8and have the nuts 13 to secure the eyes 12 i'rmly in place. Straps 14are secured by the bolts 15 and the screws 16 to one of the cleats 4.These straps have eyes 17. A U- shaped link 18 has its connecting archportion rockably mounted in the eyes 17, and the straps 14 are disposedin spaced relation whereby the upper and lower arms of said U-shapedlink 18 will engage said straps 14, in order to prevent movement of saidlink. A U-shaped link 19 has its arch mounted in the eyes 12, which areso disposed that the arms of the link 19 will engage said eyes, that is,at the points where the arms bend from the arch, thereby preventingvertical movement of the link 19. The hinged link 18 is a trifle shorterthan the link 19, so as to move between the arms of the link 19. Theadjacent `ends of the arms of the two links 18 and 19 are ,hingedly orpivotally united by the vertical bolt or rod 20, which has an integralhead 21 at one end and a nut 22 on its opposite end, thereby preventingaxial Vertical movement of said rod. When the door 6 is closed and thehingedly united links move to the positions shown in Fig. 2, the pivotof the link 18 to the straps 14 extends outwardly beyond the plane or aline @-7) between the pivot rod 20 and the pivot of the link 19 to theeyes 12, thereby holding the door closely against the shoulder 3. Inorder to open the door 6, the pivoted ends of the arms of both links 18and 19 are thrown outwardly past the pivot of the link 18 to the strap14, then the links may be moved as shown in dotted line in Fig. 3, withthe door adjacent the inner face of the wall of the silo, as also shownin dotted lines in Fig. 3.

The invention having been set forth, what is claimed as new and usefulis 1. In a silo door hinge, a pair of straps spaced at a considerableinterval one above the other and secured to the frame of the dooropening, a U-shaped link having its arch rockably mounted in eyes ofsaid straps, eyes spaced at a considerable interval one above the otherand carried by the outer face of the door, a second U-shaped link havingits vertical arch rockably mounted in said eyes, means pivotally unitingthe arms of both links, said strapsY having eyes in Which the first linkis mounted" beingso'cone'- structed and disposed that the pivot of thethe first link in the eyes of said straps will.

protrude outwardly out of alinement With th'e'pivots fbetweenfloothlinks and* the pivot of the second link to thedooryto hold vthe door inclose contact With a shoulder of the door opening.

2. In -a vsilo door1hinge,a pair of straps spaced ata considerableintervalone above thevother and securedto the frame of the door opening,:a vU-shaped linkahavingits arch rockably mountedy in vthe eyes ot saidstraps, eyesfspaced at a considerable interval one abovethe other andcarried by the outer"- face-of the door, a second U-sh'apedlinkhavoutwardly out of alinement Withthe pivots betweenboth links` andthe pivots of the Second link to the door, to hold the door in closecontact With a shoulder .of the door opening.
